Type: Avidity‑sensing Subtype:
Multiple low-affinity interactions give rise to high-avidity interactions that have increased binding strength, with more than additive affinity.
CD3E_HUMANLIG_TYR_ITAM185202Phosphorylation of Y188 and Y199 in the ITAM motif of T-cell surface glycoprotein CD3 epsilon chain (CD3E) induces high-avidity binding to the tandem SH2 domains of Tyrosine-protein kinase SYK (SYK).

details

Type: Specificity Subtype: Altered binding specificity
The balance of the competition for overlapping or adjacent, mutually exclusive interaction interfaces is tipped in favor of one of the interactors by PTM-dependent modulation of the intrinsic affinity of a binding region. Multiple, successive PTMs allow sequential switching of different binding partners in an ordered manner by step-wise alteration of binding specificity.
CD3E_HUMANLIG_SH3_5184188Phosphorylation of T-cell surface glycoprotein CD3 epsilon chain (CD3E) by Lck (Tyrosine-protein kinase Lck (LCK)) during T cell activation switches the specificity of CD3E from SH3 domain containing proteins like Epidermal growth factor receptor kinase substrate 8-like protein 1 (EPS8L1) to SH2 domain containing proteins like Tyrosine-protein kinase ZAP-70 (ZAP70).

details

Type: Binary Subtype: Allostery
The binding properties of a motif or a motif-binding domain are modulated indirectly by allosteric effects resulting from PTM or effector binding at a site that is distinct from the actual interaction interface.
CD3E_HUMANLIG_SH3_5184188Ligand binding to the T cell receptor complex TCR-CD3 results in a conformational change that exposes an SH3-binding motif in T-cell surface glycoprotein CD3 epsilon chain (CD3E), resulting in recruitment of Cytoplasmic protein NCK2 (NCK2), involved in T cell activation.
